Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 218 Issued at 2200Z on 05 Aug 2020
IA. Analysis of Solar Active Regions and Activity from 04/2100Z to
05/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 1 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
with a slight chance for a C-class flare on day one (06 Aug) and
expected to be very low on days two and three (07 Aug, 08 Aug).
IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 618 km/s at 04/2202Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 2815 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (06 Aug, 07 Aug) and quiet to
unsettled levels on day three (08 Aug).
